Great Pix

So can you tell me if there were anything other than KLH monitors in the control room? Are there any pix that show each wall of the control room? What is the evolution in terms of multitracks:

- mono and 2-track are obvious, but how long was the 3-track in use? Did the studio go straight to 8-track or was 4-track in between? How hot was that CR with all that tube gear? Was the lathe in the same room or a dedicated room?
